How we use cell phones is changing.  Cell phones have evolved beyond voice calls and are now becoming the preferred means of communication for Internet access and email on the go. Cellular Coverage within buildings is now expected to be ubiquitous.  In 2012 more than 75% of cellular calls began or ended within a building.  In 2014 mobile data traffic reached levels rivaling traditional Internet traffic.  To stay competitive in the marketplace,  DAS networks (distributed antenna systems) are now a necessary part of future planning in hotels, convention centers, office buildings, and educational campuses.

DAS is a series of antennas which extend the coverage and capacity of cellular and public safety networks into buildings and outdoor areas. Our Advanced Wireless Solutions team has two decades of experience in the wireless and RF industries designing and integrating wireless communications and have embraced the critical emerging DAS industry. AWS can design and install your DAS network in new construction as well as the business critical building retrofits needed to keep your facility and your business viable in the new marketplace.

What is DAS?

DAS-Escalator--medDAS is the acronym we use in the wireless industry for DISTRIBUTIVE ANTENNA SYSTEM or DISTRIBUTED ANTENNA SYSTEMS (DAS). A Distributive Antenna Solutions can connect to a variety of wireless services and then rebroadcast those signals throughout the areas in which the system is installed. The applications can include cellular service from multiple wireless carriers, public safety radio frequencies, and Wi-Fi. Campus style environments can benefit greatly from DAS systems. In a medical clinic or hospital the special medical wireless systems it uses also can be supported with a DAS solution as well as cellular, Wi-Fi, and public safety.
To understand how a DAS operates, it helps to know some of the methods by which wireless signals are propagated. Nearly all of us know what a cell tower looks like; well, each of those towers carries antennas for one or more macrocells (multiple carriers when there are “layers” of antenna arrays). Wireless carriers use microcells to add capacity in areas with a high density of mobile wireless device users. In a DAS setup, any or all of these technologies may come into play.

Now that we know we’re “inserting” signals, the next logical step is to think about what we’re doing with them. Every DAS has a “head end” into which these source signals are combined for distribution. The signals are amplified and carefully “combed” together as needed, in the electronic equipment and filters at the head end. Intermediate amplifiers (usually referred to as bi-directional amplifiers or BDAs) are added to make up for signal losses due to the physical limitations in how far a cable can carry the signal.

Cables then carry the signal out to passive antennas placed where more signal strength or coverage is needed. A DAS might use fiber from the head end to the remote BDAs, plus coaxial or shielded Category 5/6 cable from there.

One of the selling points of a DAS is that a properly designed and installed system is able to support all your wireless traffic: Wi-Fi, cellular, PCS, paging, maintenance, and public safety. Just be aware that each of these technology types uses different radio frequencies, which directly affects the DAS design and the type of antennas to be installed in the buildings. It is best to decide in advance which wireless systems the DAS needs to support.

das-hospitalHospital Facilities

In the health care industry, specifically in the hospital environment, Doctors and Healthcare professionals are relying more on  tablet communications even in operating rooms, labs, elevators and stairwells.  This growing demand is being challenged by today’s building design that utilize Low-E glass and new building materials that degrade cellular signals. A ‘distributed antenna system’ (DAS) is designed to amplify cellular signals throughout the building.

Mobile Healthcare Applications

In today’s Health Care industry the need for seamless and robust cellular coverage is critical for health care workers to be efficient and effective.  Doctors and Healthcare Staff and Technicians require facilities with robust wireless coverage for today’s medical information sharing technologies.
